I believe this affects resources and providers, not recipes.

% grep -r 'class File ' *

chef/provider/file.rb:    class File < Chef::Provider

chef/resource/file.rb:    class File < Chef::Resource

BTW, I was writing my thoughts on this and fired up chef-shell to try it.

And guess what, this works like a charm in recipe_mode without any ::

chef:recipe > file "test" do

chef:recipe >     not_if { File.exists?("test") }

chef:recipe ?>  end

Are we even sure this is still a problem or are we cargo-culting something that is in the past?!

Noah, I suppose that it MUST be a choice of core team. This is a missed usability issue.

Make a patch and open a ticket and I'm sure btm and crew will be glad to take a look :) It might need to wait for a major release since it would be a backwards-incompatible change, but this would only affect people subclassing the file resource I think, which should be somewhat rare so maybe we can just put out a warning.
